7, Fat table caused by read and write failure
The Fat table records the storage address of the hard disk data, and each file has a set of connected fat chains that specifies the cluster address to which it resides. The corruption of the fat table means the l
mode, in fact, the serial technology is faster than the transmission speed of parallel technology.
Easier cabling-the flat, wide line of SCSI cables will no longer be used.
Wider scalability-compatible with SATA.
Lower costs-with the advantage of simplifying the internal connectivity design, you can reduce design costs by sharing components.
Look at this picture, this is the image of the SAS hard drive. Th

Although the desktop can use a notebook hard disk, in turn, the notebook is not able to use the 3.5-inch standard desktop hard disk, because the internal space of the notebook is limited, the hard disk size is designed for 2.5-inch small
When the computer suddenly crashes or loses power, is the hard disk data lost? Did the important USB flash drive files be accidentally deleted? Computer poisoning, file loss or unreadable? The system suddenly crashes and important files are lost? The most feared use of computers is the loss of important data due to sudden and catastrophic failures, misoperations, computer virus attacks, hardware faults, and
Summary of processing process
1. After changing the bad hard disk, the system recognizes the primary, the original main disk is invalid, if the replacement of the old disk will be inserted into the system will cause confusion, resulting in the system, dial out is useless.
2.smart error does not prompt, this time is using the System test program (boot F10) that measured out the error.
3. Two hard drives o
First you need to know how big the 128G size is. We calculate by the actual size, is 128gx0.9313≈119.2g. 119G in the system disk occupies about 20G size, that is, the remaining 100G size. These are the actual sizes that can be used.
100G hard disk size If your computer is used to watch movies, download some movie dramas or use them for video capture and editing. It may not be enough. Because the general vi
